FLUID-FUEL BURNER.

SPECIFICATION forming part of Letters Patent No. 783,455, dated February 28, 1905.

Application filed February l0| 1904. Serial No. 192,882.

To cbZZ whont t may concern:

Be it known that LFREDEEICK L. MCGAHAN, a citizen of the UnitedStates, residing at the city of St. Louis, in the State of Missouri, have invented a certain new and useful Fluid-Fuel Burner, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it `appertains to make and use the same. reference being had lto the accompanying drawings, forming part of this specication.

My invention relates to new and useful improvements in burners for oil or other similar fuels, and also to improvements in the casing in which the burner is supported,whereby the air admitted to the combustion-chamber is easily and accurately controlled and is supplied to the burner at such points as to obtain the best results in com plete combustion and intense heat.

ln the drawings, in which like characters of reference refer to similar parts in the several views, Figure 1 is a vertical longitudinal section through an apparatus embodying my invention. Fig. 2 is a bottom plan view of the burner, the casing being removed. Fig. 3 is a top plan View of the burner and casing shown in Fig. 1,the front end of the casing being broken away and the central air-deflector omit'- ted. Fig. 4 is a vertical section on the line 4 4 of Fig. 3. Fig. 5 is a vertical section on the line 5 5 of Fig. 1. Fig. 6 is a side elevation of the burner and the air-deflectors, the surrounding portion of the casing being shown in section; and Figs. 7 and Sare views showing in longitudinal vertical section the application of my invention to a locomotive-boiler and to a stationary boiler, respectively. K

Referring now to Fig. 1, 10 represents a casing which is preferably made in two parts suitably bolted together. The horizontal portion of this casing is in the form of a slightlyflattened cylinder and the upward extension thereof is circular in cross-section. The burner itself is adjustably supported in the upward extension of the casing 10 by means of angleirons 11. These angle-irons are four in number and are held in position so as to be adjustable vertically by means of the bolts 12, passing through longitudinal slots in the casing 10. The base 14 of the burner is circular and is provided at its periphery with an annular flange 15. Ooncentrically disposed upon the base 14 within the flange 15 is a hollow truncated cone 16, in the outer surface of which are formed a number ot' circumferential grooves 17. Between the cone 16 and the flange 15 is formed the catch-basinlS. Situated concentrically within the truncated cone 16 is a second hollow truncated cone 20, an upward eX- tension of which projects through the o'pening in the top of the hollow truncated cone 16. Between the two cones 16 and 20 is a fuel-chamber 21. A rod 23 passes through a central perforation in the base 14. The upper end of this rod 23 extends through the opening at the top of the cone 20 and is provided with a flaring deflector 24. The lower end of the rod 23 passes through a perforation in the casing 10 and is'made adjustable by means of a set-screw 25. Formed concentrically in the under side of the base 14 is an annular groove in which is a shutter 27, adapted to rotate about a boss 28 surrounding the perforation, through which the rod 23 passes. The openings in the shutter 27 correspond with similar openings in the base 14 to regulate the admission of the air into the hollow cone 20, as hereinafter described. The shutter 27 is adjusted by means of a suitable rod 29, the end of which passes through a slot 30 in the door 31, with which the end of the horizontal extension of the casing 10 is provided. This door 31 is hinged to the upper side of the casing 10 and is provided at its lower side with a pivotallyoperating handle 32. This handle 32 is provided with a bent-forward extension 33 in the form of a pawl, which is adapted to engage with a number of teeth 34, formed on the under side of the casing 10. The handle 32 being heavier than the extension 33 the device will operate to hold the door 31 in any desired position. This end of the casing 10 is also provided with a depression 35, from which leads a waste-pipe 36, Fig. 5. The inner end of this waste-pipe projects a slight distance above the bottom of the depression 35.

A supply-pipe 37 for the oil or other fluid passes through the side of the horizontal cxtension in the casing 10 and leads through the IOO Ycasing 10.

base of the burner 14 into the fuel-chamber 20. rlhe base of the burner 14 is also provided, as best shown in Figs. 2, 3, 4, and 6, with a number of sets of radially-projecting lugs 40. These lugs 40 are adapted to receive between them, as best shown in Figs. 3, 4, and 6, the downwardly-extending ends of a number of air-deilectors 41. The downwardlyextending ends ofv these air-deflectors 41 rest upon the upturned ends of' U-shaped pieces 43, which are in turn supported and made adjustable by means of set-screws 44, passing through the sides of the casing 10. Nuts 45 serve to lock these set-screws in position. The inner ends of the set-screws 44 are beveled and are adapted to engage with the beveled under sides of the U-shaped pieces 43.

Fig. 7 shows one way of adapting my invention for use with the {ire-box 47 of a locomotive. In this instance the door of the casing 1() is represented as situated at the rear side of the lire-box 47. After the casing 10 has been inserted in the fire-box 47 the lirebox vis preferably partiallylilled with a refractory material 48, such as a mixture of fireclay and asbestos fiber, which is put in in a plastic state and which afterward hardens to form an air-tight union between the casing 10 and the lire-box 47, so that all the air which enters the fire-box 47 must do so through the The admission of the oil to the burner from the tender 49 is controlled by means of a handle 50, situated in the eab 57 and suitably connected by means of a rod 51 for operating the valve 52 in the pipe 37. The adjustment of the shutter27 is accomplished by means of a handle 53, also situated in the cab 57 and suitably connected by rods 54 and 55 and the bent lever 56 for operating the same. The position of the door 31 is also regulated by means of a handle 58 in the cab 27 and suitably connected by means of rods 59 and 60 and the bent lever 61 for operating the same.

Fig. 8 shows my invention adapted for use in the lire-box 63 of a stationary boiler. In

vthis instance, as in the apparatus shown and said fuel-chamber 21 into the grooves 17 and will thence flow into the catch-basin 18. A little oil is then lighted in the depression 35, which serves as a lightingpan. The flame as it escapes through the casing 10 around the burner will light the oil at the top of the burner. As the burner is thus heated the oil in the fuel-chamber 2l will escape through the opening at the top of said chamber in a gaseous state. At this point it mixes with the air supplied through the interior air-passage Jformed by the hollow truncated cone 2O and also'with the air supplied through the air-passage between the burner and the casing 1() and deliected inwardly by the deiiectors 41. When the mixed fuel is lighted at this point, perfect combustion will take place. The quantity of air admitted to the burner and its direction are adjusted by means of the door 31, shutter 27, and air-deflectors 24 and 41, and the position of the burner'itself in the casing 10 is regulated by means of the bolts 12, so that the best results in combustion are produced.
